STMicroelectronics M95P08-x Ultra-Low-Power Serial SPI Page EEPROMs

STMicroelectronics M95P08-x Ultra-Low-Power Serial SPI Page EEPROMs feature advanced proprietary NVM technology. M95P08-x offers byte flexibility, page alterability, high page cycling performance, and ultralow power consumption equivalent to EEPROM technology. These 8-Mbit SPI page EEPROM devices are organized as 2048 programmable pages of 512 bytes each and are accessible through an SPI bus with high-performance dual- and quad SPI outputs. The devices offer two additional (identification) 512-byte pages: one contains identification data and, upon request, the UID; the second can be used to store sensitive application parameters (can be permanently locked in read-only mode). Additional status, configuration, and volatile registers set the desired device configuration, while the safety register provides information on the device status.

M95P08-I operates with a supply voltage from 1.6 to 3.6 V over an ambient temperature range of -40°C to +85°C. The M95P08-E offers a -40°C to +105°C extended temperature range and supports a clock frequency of up to 80MHz. STMicroelectronics M95P08-x Page EEPROMs feature byte and page write instructions of up to 512 bytes. The write instructions consist of self-timed auto-erase and program operations, resulting in flexible data byte management. Page/block/sector/chip erase commands are also accepted and set the memory to an erased state. Memory can then be fast-programmed by 512-byte pages and further optimized using the Page program with buffer load instruction to hide the SPI communication latency.
